... This application shows, however, some operative limits due to dissipation and current capability of the output stage. For this reason, we reccomend to use the TDA7265 in bridge with the supply volt- age equal/lower than 16V when the load with higher loads (i.e.16 ), the amplifier can work correctly in the whole supply voltage range ...
